You feel burdened by the need to interact with others, but are unable to avoid it for practical reasons. Indeed, people vary in the extent to which they desire interaction, and that is natural. It is rare for someone to intensely desire separation.
The book of Tanya is a basic text of Chassidic teaching. Rabbi Shneur Zalman, the author of Tanya, quotes the prophet Malachi, who says ‘One father to all …,’ meaning all the souls are from the same source. Spiritually, the souls are actually joined, and since the physical world conceals the spiritual energy that maintains it, we are not aware that actually we are all one. In truth, our souls are burning to reveal the spiritual bond we have. The Baal Shem Tov, founder of the Chassidic movement, also taught us that our souls descend to this world for the express purpose of helping one another. It appears that something is causing you to be out of touch with the natural desire to bond with others, be it only a select few. Perhaps there have been difficult experiences… King Solomon, in the book of Proverbs, recommends talking out our issues with an understanding person, friend or mentor. May you have good news regarding your progress!
